CVE-2026-23264

MEDIUM

Revert "drm/amd: Check if ASPM is enabled from PCIe subsystem"

Title source: cna
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: Revert "drm/amd: Check if ASPM is enabled from PCIe subsystem" This reverts commit 7294863a6f01248d72b61d38478978d638641bee. This commit was erroneously applied again after commit 0ab5d711ec74 ("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device") removed it, leading to very hard to debug crashes, when used with a system with two AMD GPUs of which only one supports ASPM. (cherry picked from commit 97a9689300eb2b393ba5efc17c8e5db835917080)
